WARNING Before applying power to this instrument, make sure it has been properly grounded through the protective conductor of the ac power cable to a socket outlet provided with protective earth contact. Any interruption of the protective (grounding) conductor, inside or outside the instrument, or disconnection of the protective earth terminal can result in personal injury.

The HP 71209A - At A Glance The HP 71209A modular spectrum analyzer has a full-band sweep from 100 Hz to 26.5 GHz and built-in external millimeter mixer capability. The standard system consists of an HP 70909A RF section, the HP 70004A color display, the HP 70001A mainframe, the HP 70900B local oscillator module, the HP 70902A and HP 70903A IF sections, and an HP 70310A precision frequency reference.

These softkeys are also dependent upon which menu softkey is selected and can have several levels, each accessed by pressing the bottom softkey.
In This Book About This Book This HP 71209A Modular Spectrum Analyzer Quick Start Guide provides step-by-step instructions for some of the most common tasks for the HP 71209A modular spectrum analyzer. How To Use This Book Start with the quick overview of the product on the preceding two pages of this book.

Make sure that the spectrum analyzer is set to a known state by Example 1. Set up and setting up and initializing the system with this example. This initialize the system ensures that the local-oscillator module is in control and that the menu softkeys that contain the spectrum-analyzer functions are displayed.

NEXT INSTR DISPLAY display appears. This key sequence should display the HP-MSIB address of the HP 70900B local-oscillator (master) module at the bottom of the display screen when the spectrum-analyzer display appears. For example: Row 0 Column 18: 70900B,Lo/Ctlr 3.
INSTR PRESET 1. Press The HP 71209A modular spectrum analyzer is placed in a known state by setting all spectrum-analyzer functions to their preset state. 2. Connect the 300 MHz CALIBRATOR output to the RF INPUT connector on the HP 70900B front panel.

After the routines are nished, the instrument resumes the state at which the calibration routines were initiated. In this case, the instrument-preset state is resumed.

A carrier-to-noise measurement can be made very simply by using Example 5. Make a the delta-marker function. This can be demonstrated by using the carrier-to-noise calibrator signal, placing a marker at the peak of the signal, then measurement placing a delta marker somewhere in the noise. The carrier-to-noise measurement result is displayed in the active function area and is normalized to a 1 Hz bandwidth.
Page 20
Pressing NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN turns on the marker-noise function. MKNOISE On Off The spectrum analyzer enables sample detection mode and performs a digital average for 16 bits around the active marker. The marker readout in the active function area on the display reads out the dierence between the markers in dBc/1 Hz.

The dierence between two traces can be measured very easily Example 6. Measure using the delta-marker function. This example demonstrates the the difference between delta-marker function while measuring the calibrator signal when it is two traces connected and not connected. 1.
